Fun4Kids is a developer of educational Android apps for children that are three to seven years old. Fun4Kids offers more than fifty apps for learning basic mathematics, reading, and spelling. While browsing through the gallery of Fun4Kids apps you will also find some memory games and puzzle games.
A couple of the Fun4Kids apps that I recommend starting out with are Kids Math and Preschool All Words. In Kids Math children learn to recognize numbers up to fifty through guided counting and a simple memory game. In Preschool All Words children practice spelling familiar three to five letter words. Despite the name “Preschool All Words” the app is actually better suited to children in first grade. These apps will give a good feel for the format of the Fun4Kids apps without spending money on any apps. If you decide that you like the apps then go ahead and buy the full version of the apps.
